Keller himself credits the many people responsible for the contributing parts [0]. I think the general 'enthusiast' tech press and reporting likes hero figures and the simplicity it brings, even better when you can cast a good guy against a bad guy, and the background in this case would be AMD vs intel.

Humans inherently like having a narrative. When we discuss historical events, we typically want to have a clearly defined leader and/or visionary upon whom to pin events. Without this, our imaginations aren't as engaged, and therefore emotions aren't stirred. For example, the stories of early game companies are great because the teams were very small, a narrative can be written, and the product was fun. With modern games, budgets are massive, teams are massive, and things are often designed and approved by committee. The result can be beautiful and fun, but the story getting there isn't as entertaining.

This is the same reason we have trouble erecting defenses against "the banality of evil" etc. When the villain wears a monocle and smokes a cigar, everybody hates them. When the villain is a misaligned structural incentive, a million people can die and politicians and the media will start rounding up scapegoats instead of actually changing the incentive.
